Forces of Change

Nearly every scientific and social issue confronting us today involves change: climate change, ecological change, cultural change. What forces drive these changes? What is the tempo and mode of these changes? Are these changes natural or the result of human tampering? Are they to be feared or welcomed? How do we - and all life on this planet - adapt to these changes? Come and explore the answers to these and other important questions with us.

The Smithsonian’s National Museum of Natural History recently acquired an 80,000-specimen collection of bark beetles donated by the late Stephen L. Wood, Brigham Young University professor of Entomology, and former reigning expert on the bark beetles.

The Stephen L. Wood collection brings the collection of bark beetles held in the Natural History Museum’s Department of Entomology to an impressive 180,000 specimens, making it one of the most extensive collections in world.

“The Smithsonian’s collection is arguably the most important bark beetle collection in the world,” says David Furth, entomology collections manager at the Natural History Museum. “We are proud to have the S. L. Wood beetles join our collection.”
